heater control parts, anybody make these

Hi y'all,

Anybody make Repops of the nylon plastic pin,clip, roller things for the heater controller on the NON A/C cars that the heater control cable ends snap into? Mine are so dryrotted theres nothing left of them. What are these even called?

They actually would be better if they were made out of steel, and had a clevis pin instead of the cheesy built in clip that breaks.
